About Resolved Markets
Resolved Markets is an independent data platform operated by Elcara LLC-FZ. We capture high-frequency orderbook snapshots and trades from Polymarket prediction markets and Hyperliquid perpetual futures, then expose that data through REST, WebSocket, OpenAPI, CLI, and MCP interfaces for research and agent workflows.

What we do
Prediction markets and perpetual futures move fast, but the raw orderbook data that drives them is rarely preserved in a form researchers can actually use. Resolved Markets fixes that. We continuously record the full bid and ask sides of every market we track, store each snapshot with millisecond timestamps in ClickHouse, and serve the archive back through interfaces built for both humans and machines.
The result is a high-fidelity historical record you can query in seconds: best bid and ask, mid price, spread, depth at every level, and the individual trades that crossed the book. Whether you are validating a market-making model, studying how odds shift around a resolution, or feeding live context to an AI trading agent, the underlying data is consistent, time-aligned, and reproducible.
- REST API — paginated historical snapshots, live orderbooks, market summaries, and trade history.
- WebSocket feed — real-time orderbook updates streamed as they happen.
- MCP server — native Model Context Protocol access so AI agents like Claude can query markets directly.
- CLI & OpenAPI — a command-line tool and a full OpenAPI 3.1 specification for fast integration.
How the data is captured
Capture is event-driven rather than polled. We hold persistent WebSocket connections to each venue and write a new snapshot whenever the book actually changes, throttled to avoid duplicates. Polymarket crypto markets are sampled at roughly 20 snapshots per second per token, sports markets at about 2 Hz, and Hyperliquid perpetual L2 books once per second. Crypto reference prices stream in parallel from Binance so every snapshot carries the spot context around it.
Each snapshot preserves two timestamps — the event timestamp emitted by the exchange and the capture timestamp recorded on our side — alongside monotonic sequence numbers. Together these let you measure end-to-end latency and detect any gaps in the stream, which matters when you are reconstructing exactly what the market looked like at a given instant.
Who uses Resolved Markets
Quantitative researchers use the archive to backtest prediction-market and perpetual-futures strategies against real depth and spread, instead of synthetic or end-of-day data. Developers embed live and historical orderbooks into dashboards, alerting systems, and trading tools. And AI-agent builders connect the MCP server so language models can reason over current market state and historical context without bespoke plumbing. Coverage spans crypto, sports, economics, weather, social, and equities prediction markets, plus Hyperliquid perpetuals.

Frequently asked questions
What is Resolved Markets?
Resolved Markets is an independent data platform that captures high-frequency orderbook snapshots and trades from Polymarket prediction markets and Hyperliquid perpetual futures, then exposes that history through a REST API, a WebSocket feed, an OpenAPI specification, a command-line tool, and a Model Context Protocol (MCP) server. It is built for quantitative researchers, developers, and AI agents that need clean, time-stamped market microstructure data for backtesting and analysis.
Who operates Resolved Markets?
Resolved Markets is operated by Elcara LLC-FZ, a company registered in Dubai, UAE at Meydan Grandstand, 6th floor, Meydan Road, Nad Al Sheba. We are an independent third party and are not affiliated with, endorsed by, or operated by Polymarket, Hyperliquid, Binance, Kalshi, or any exchange we collect data from.
How is the data captured?
We maintain persistent WebSocket connections to each venue. Polymarket crypto orderbooks are sampled at roughly 20 snapshots per second per token using event-driven triggers, sports markets at about 2 Hz, and Hyperliquid perpetual L2 books once per second. Every snapshot preserves both the event timestamp from the exchange and our capture timestamp, plus sequence numbers for gap detection, so you can measure latency and verify data continuity.
Does Resolved Markets place trades or hold funds?
No. Resolved Markets is a read-only data layer. We do not custody funds, route orders, or execute trades on any venue. The platform only records, stores, and serves public market data for research, analytics, and AI-agent workflows.
How do I get started?
Create a free account, generate an API key, and call the REST API or connect the MCP server to an AI agent such as Claude. The free tier includes BTC markets and 24 hours of history; paid tiers unlock all categories, full orderbook depth, longer history, and exchange data. See the API docs and pricing pages for details.
